COOKING-STOVE.

SPECIFICATION forming part of Letters Patent No. 369,677, datedSeptember 13, 1887.

Application filed May 4, 1885. Serial No. 164,337.

To aZZ whom it may concern:

Be it known that l, EDGAR W. ANTHONY, of Boston, in the county ofSuifolk and State of Massachusetts, a citizen of the United States, haveinvented a new and useful Improvement in (looking Stoves and Ranges, ofwhich the following is a full, clear, and exact description, referencebeing had to the accompanying d rawin gs,for1nin g a part of thisspecification, in explaining its nature.

It is very desirable to introduce into a bakingoven while the process ofbaking is going on a fresh supply ot'air. This air must be introducednot in large quantities, or in a way to materially affect thetemperature of the oven, but in the form of a spray, if air can be saidto take such form, produced by drawing through very fine perforations orholes; and it is also necessary, in order to maintain this infusion offresh air, that the heated air, or air which rises to the top of theoven, should be allowed to escape, but not too rapidly; and for thispurpose it is also desirable to furnish very fine holes orperforations',through which it shall pass in its escape.Thisintroduction of the outer air and circulation thereof within theoven produces a marked effect upon the article or thing being cooked.

My invention relates to that class of cooking-stoves the ovens of whichare supplied with a limited quantity of fresh air, so that they may beproperly ventilated while the process of baking is going on, the objectof my invention being to provide a construction which will obviate someof the objections to stoves of the class referred to heretofore in use.This object I accomplish by providing the back plate of the oven with aseries of vertical openings extending substantially the full height ofthe said plate, the said openings being covered by fine wire-gauze or byfinelyperforated plates; and to permit of the use of a back plate thusconstructed the back of the stove is formed with an overhanging curvedportion,between which and the top portion of the back plate is an openspace,which permits of the proper escape of the heated air from the topportion of the oven through the upper portions of the wire gauze orperforated plates covering the openings in the said back plate.

Referring to the drawings,Figure 1 is a per- (No model.)

spective view of a six-hole range, showing especially the back and endthereof to illustrate the application of my invention. Fig. 2 is a viewin vertical section upon the line 00a: of Fig. 3, also showing inelevation parts beyond this line. Fig. 3 is a vertical central sectionupon the line y y of Fig. 2.

The invention is represented as applied to a six boiler hole range.

Ais the ash-pit; B, the fire-pot; O,the space between the top plate ofthe oven and the top plate of the stove,through which the products ofcombustion pass. D is the downflue; E, the upflue; F, the oven; G, theoven-door; H, the box into which the downflue enters, and which isconnected with the sp'aceC by the opening in the plate 0, which isadapted to be closed by a damper. M is thebase-plate of the oven; M, thefront plate; M", the rear side plate, and M the back plate.

It will be observed from this description that the oven is surroundedupon the top,bottom, and back side by the flues D and E, that the frontside is occupied by the door,that the back of the oven has no flue, theback plate being ofa single thickness, and it is in this plate that Ihave arranged the openings N, which extend from the lower edge or nearthe lower edge of the plate upward to the upper edge or very nearly tothe upper edge of the plate. As many of these openings may be used asdesirable. They are partly closed by very fine wire-gauze O,asrepresented in Figs. 1 and 2, or by veryfinelyperforated plates 0', asalso represented in said figures. The openings are entirely closed bythe plate or plates P, which slide in ways 1) upon the outside of theplate, and which is or are moved by the handle 19 into position to coverthe openings and out of position to uncover them.

In order that the openings may extend to or very nearly to the top ofthe back plate and so as to.connect the upper portion of the oven withthe outer air, I have. formed the inner wall, R, of the box H asrepresented in Fig. 3, or so as to be inclined or extend outwardly froma point on a line with the top plate of the oven, and so as to formbetween the Wall and the back plate the recess or space S. I haveselected as the best place for the arrangement of these openings theback plate of the oven,

as this is a portion of the stove which is not open or exposed to view,because the box H projects sufficiently to cover the openings and toprevent ashes or dustfrom clogging the perforations. It is also out ofthe way.

Iam aware that it is not new to provide the oven-d oor with openingsfilled with wire-gauze, through which fresh air enters and the heatedair leaves the oven; but I consider that the arrangement or location ofthese openings in the door is objectionable for these reasonsfirst, theyhear such a relation to the room and to the top of the stove and'theash-pit that they very soon become clogged by the accumulation of dustand dirt,which finds a ready lodgment therein; second, it detracts fromthe general appearance of the front of the stove; third, the stove-doorshould always be solid or unprovided with openings.

Of course the shape of the openings may be modified or changed withoutdeparting from.

the spirit of my invention or the essential features thereof.

I am aware of Patent No. 272,912, granted to J .W. Thomas, dated March13, 1883,which describes a series of holes arranged in the oven-door, aplate forming the rear wall of the oven and also the patent to Dennis G.Littlefield, No. 313,874, dated March 17,1885, which shows and describesa stove-door or stationary wall of the oven having air-inlets and anair-outlet into the escape-flue of the stove; but I consider that thesepatents do not describe or contain the features of myinvention, in thatthe air inlet and outlet are not arranged in the back plate ofthe stove,and there only, and because they are arranged in the door of the stove,which, as I have abovestated,lconsider to be objectionable, and alsobecause they open into the fines of the stove, which I consider notdesirable and do not use; and I therefore do not claim the inventionsset forth' in these patents.

with a curved plate, R, .and forming the rep cess or space S between itand the back plate of the stove, as and for the purposes described.
